Is the Ball valve with steel lever with GW BSP/GZ BSP, type 4331 compliant with PED 2014/68/EU for industrial installations?

Yes. Ball valve with steel lever with GW BSP/GZ BSP, type 4331 is compliant with PED 2014/68/EU for industrial installations. The product description explicitly states it "meets the requirements of the PED directive 2014/68/EU." Ensure that the specific pressure/temperature rating and materials (nickelâplated brass body, chromeâplated brass ball, PTFE sealing, NBR stem sealing) are suitable for your media and operating conditions, and verify applicable conformity assessment module and documentation (pressure equipment category, declaration of conformity, and any required CE marking) for your installation.

Can the Ball valve with steel lever with GW BSP/GZ BSP, type 4331 be used with aggressive chemicals given its nickel-plated brass body and PTFE seals?

Ball valve with steel lever with GW BSP/GZ BSP, type 4331 can be used with many chemicals but only if compatibility with its materials is confirmed. Its nickel-plated brass body and chrome-plated brass ball offer moderate corrosion resistance but are not suitable for strongly corrosive media (e.g., strong acids, ammonia, some halogenated solvents). PTFE ball seals provide excellent chemical resistance for most aggressive chemicals, while NBR stem sealing is less resistant (poor with ketones, some chlorinated solvents, strong acids/alkalis). Operating range is â20Â°C to +110Â°C and pressure rating falls with temperature. Before use with aggressive chemicals, verify chemical compatibility for brass, chrome/nickel plating and NBR at your temperature and concentration; if incompatible, choose a valve with more resistant materials (e.g., stainless steel body, FKM/EPDM/PTFE seals).

What is the maximum allowable operating pressure of Ball valve with steel lever with GW BSP/GZ BSP, type 4331 at different temperatures?

Ball valve with steel lever with GW BSP/GZ BSP, type 4331 Maximum allowable operating pressure varies with temperature due to materials (nickelâplated brass body, chromeâplated brass ball, PTFE seals, NBR stem seal). For the stated operating temperature range (â20 Â°C to +110 Â°C) typical maximum pressures are as follows (general guidance based on common material limits; verify with manufacturer data for exact values): - At temperatures up to 20 Â°C: maximum allowable working pressure â 16 bar. - From 20 Â°C to 60 Â°C: maximum allowable working pressure gradually reduces; approximate safe pressure â 10â16 bar (commonly ~16 bar at 20 Â°C decreasing toward ~10â12 bar by 60 Â°C). - From 60 Â°C to 100 Â°C: further reduction in allowable pressure due to PTFE and NBR softening; approximate safe pressure â 6â10 bar. - At maximum operating temperature around 110 Â°C: allowable pressure is typically reduced to â 4â6 bar. Notes: These figures are indicative and depend on media, system safety factors and applicable standards (PED 2014/68/EU). For precise maximum allowable pressures at specific temperatures, consult the valve manufacturerâs pressureâtemperature rating chart.
